tested with NR, NR/SBR, CR, NBR, EPDM, ACM and CSM compounds • Static T -test results indie similar adhesion as compared to standard RFL dips • Peel-tests further helped to identify the specific RF - and RFL-free systems with comparable adhesion and rubber coverage • As an outlook, dynamic shear adhesion failure tests are planned

Influence of Coupling Agent on Properties of Carbon Black

NR/SBR blend compounds with different rubber compositions were compared. Bis-(3-(triethoxysilyl)-propyl)-te-trasulfide (TESPT) was used as the coupling agent. For the SBR specimens, the modulus and tensile strength were enhanced by adding the coupling agent although the elongation at break was reduced. For the NR/SBR specimens, the crosslink density and modulus were enhanced by adding …

Rubber Compounding - an overview | ScienceDirect Topics

The best of these is carbon black; other fillers give very inferior properties in SBR to those achievable in a corresponding natural rubber compound. Resistance to abrasion, and degradation under heat is better for SBR, but: as it is less chemically reactive it is also slower to cure, requiring more accelerators. Scorch problems are less likely to occur with SBR than with NR especially with

Determination of the Mechanical Properties of Rubber by FT-NIR

7/3/2016· In this paper, selected rubber materials, for example, natural rubber (NR) and some synthetic rubbers, such as styrene butadiene rubber (SBR), nitrile butadiene rubber (NBR), and ethylene propylene diene monomer (EPDM) are characterized. Their mechanical strength, that is, hardness and tensile, was analyzed by FT-NIR spectroscopy, and a PLS regression model was built as the …

Characterisation of ground tyre rubber by using

1/5/2017· The maximum degradation temperatures were strongly directive towards assuming Rubber-1 to be NR, and Rubber-2 to be SBR or BR or a mixture of the two , ; SBR and BR have overlapping degradation temperature which is why Rubber-2 was considered to be either of the two or their mixtures. Thus, further investigation was required to understand the cause of the second peak in the inert zone …

Tack and Green Strength of NR, SBR and NR/SBR Blends

A simple NR compound has superior tack compared to an SBR stock because of its greater ability to flow under compressive load and its higher green strength. The difference becomes greater as surface roughness is increased or test rate decreased. Tack differences between the two stocks can be quantitatively explained without assuming differences in the interdiffusion rate of SBR and NR
